Description

The HC38 is a version of the HC3 designed for use in NG6 (D03) stacking manifold systems. It is a compact unit weighing only 2.6 kg.

The HC38 incorporates a pressure relief valve on the high pressure side. The pressure relief valve controls the maximum allowable pressure the system can output, allowing the booster to go for a higher end pressure producing flow at the decided pressure.

Maximum outlet pressure is 500 bar in standard versions. Adjustments of the outlet pressure is carried out by varying the supplied pressure.

Functions

The basic operation is illustrated in the function diagram. The oil is fed through the connecting plate to the control valve to the IN port of the HC38 flowing freely through check valves KV1, KV2 and DV to the high pressure side H.

From the high pressure side H oil is fed to port A on the connecting plate. In this condition maximum flow through the booster is achieved giving a fast forward function. When pump pressure is reached on the high pressure side H, valves KV1, KV2 and DV will close. The end pressure will be achieved by the oscillating pump unit OP. The unit will automatically stall when end pressure on high pressure side is reached. If there is a pressure drop on the high pressure side due to consumption or leakage, the OP valve will automatically operate to maintain the end pressure.

A relief valve is installed to control the maximum allowable pressure the system can output, allowing the booster to go for a higher end pressure producing flow at the decided pressure.

Ordering an HC38

Ordering example of an HC38 with i = 4.0, DV incorporated: HC38 – 4.0 – B

Attention note!
The G-model is available in 2 variants, when ordering please specify accordingly:

  • Dynamic – low hysteresis: Ordering example of an HC38 with i = 4.0 RV incorporated: HC38 – 4.0 – G
  • Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC38 with i = 4.0 RV with opening ratio x.x incorporated: HC38 – 4.0 – G – x.x
